Flex-a-Lite 425 86-92 Toyota Supra Electric Cooling Fan - Manual (Page 3)

Step 8: (Optional) For manual switch operation, use Flex-a-lite p/n 31148. Connect the switch as shown
on the wiring diagram (previous page). Connect the "M" terminal on the control module to the "#1"
terminal on the switch. Connect the "#2" terminal on the switch to a positive 12v power source. Connect
terminal "#3" on the switch to a good ground (for switch illumination).
NOTE: To prevent thermostatic
activation (if only manual switch operation is desired), omit the lead to the "+" terminal of the
control box. "B", "G", "M+" and "M-" must remain connected. If not using a Flex-a-lite manual
switch, do not connect a ground wire to the switch!
Step 9: Use the zip ties provided to secure the wires and prevent them from interfering with fan blades,
belts, and pulleys in the engine compartment. Reconnect the battery and insert the 30 amp fuse pro-
vided.
Step 10: Insert the temperature probe into the radiator fins
Install temp. probe near inlet hose... then install the insulator cap.
Locate the inlet hose from the engine to the radiator. Remove the black insulator cap and insert the
temp. probe through the radiator fins near the inlet hose. Reinstall the black insulator cap.
If you disconnected any hoses or drained coolant to install the fan, reconnect the hoses and refill the
radiator. Press the control knob (included in wiring kit) onto the control box shaft. Turn the knob clock-
wise until it stops. Start the engine and allow it to idle. Using a hand held temperature sensor (posi-
tioned near the inlet hose) or the vehicle's temperature guage, monitor the temperature. When the cool-
ant temp. is slightly above normal (or desired temp.), turn the knob counter-clockwise just until the fan
turns on. From now on, the fan should activate at this temperature setting. Adjust as necessary to main-
tain desired temperature.
